The hit racing game Sonic & All-Stars Racing Transformed was announced to be released on iOS this winter, and it's finally here as Sega kicks off the new year.

The game takes 1.03 GB of memory, featuring a grand total of 10 racers (with more on the way). As with its predecessor, Sonic & SEGA All-Stars Racing, automatic acceleration is mandatory and graphics are toned down, but as with its console counterparts, the game also includes transforming vehicles and navigation through air, land, and sea. The most notable changes are not the somewhat overwhelming in-app purchases, but the remade World Tour and Daily and Weekly Challenges. Read the product description below:
